<p>I experienced a noticable but random lagging on the audio
when I use PulseAudio as the audio backend for the VM. At that
time I used the HDA device with additional PulseAudio sample
environment variables on the QEMU script. Now I’m using Alsa
as the audio backend and using AC97 sound on the QEMU. It
didn’t autodetected on my Windows 10 VM, but I googled for it
and I found the driver and it is working very stable. The
audio is crystal clear and no lag whatsover. I think this is
the driver that I use: <a moz-do-not-send="true"
href="http://www.driverscape.com/download/intel%28r%29-82801db-dbm-ac--97-audio-controller">http://www.driverscape.com/download/intel%28r%29-82801db-dbm-ac--97-audio-controller</a> Although
some people said that there’s no driver for AC97 in 64-bit,
mine works flawlessly and my Windows 10 is a 64-bit VM. </p>
<p>I did not search for Realtek AC97 at first, since I noticed
that from <a moz-do-not-send="true"
href="http://www.linux-kvm.org/page/Sound">http://www.linux-kvm.org/page/Sound</a> AC97
is an Intel 82801AA AC97, so I googled for “Intel 82801AA AC97
windows” and since the first link (from Intel) didn’t work for
me, I used the second one (<a moz-do-not-send="true"

Thanks for info, I am using ac97, but installed drivers without
signature, drivers from your page are not working for me on win10,
something about missing rtkvac64.sys. The problem is the same on
ac97 and on hda<br>
